The formula we use would be the graham's law. We do as follows:
<span>E_Kr / E_Ne = sqrt ( M_Ne / M_Kr)
</span>
<span>= sqrt ( 20.1797 g/mol / 83.798 g/mol ) </span>
<span>= sqrt (0.24081) </span>
<span>= 0.4907
</span>
Hope this answers the question. Have a nice day.
<span>Answer:
W must be 5-chloro-2-methylpentane. It can give only 4-methy-1-pentene (Y) upon dehydrohalogenation:
X must be 4-chloro-2-methylpentane. Dehydrohalogenation yields both Y and 4-methyl-2-pentene. (Z)</span>
Answer:
An Mg atom donates one electron to each of the two Cl atoms.
Explanation:
Chlorine is a non-metal halogen and does not have the ability to donate electrons, on the contrary, it picks them up. In fact it is almost the most electronegative of the periodic table, below the fluoride that is the most.
The chlorine then accepts one electron per magnesium to form the magnesium chloride being its formula MgCl2.
Magnesium is a metal of group two and it does yield electrons, in this case it can only yield 2 (group 2 of the Periodic Table) forming the Mg 2+ cation
Mg2+ + 2Cl- ------> MgCl2
Answer:
Explanation:
Amplitude, or the size of the wave height, affects the loudness. Larger the amplitude, the louder the volume. Period, or the time it takes for the wave to complete one round, determines the pitch. Shorter period (or higher frequency) means higher pitch.
Not sure if I’m right, but it’s probably the water level where it started to become a drought, and it left lines.
